GAS-BURNER FOR COKE-OVENS.

To all whom it may concern:

Be it known that I, ROBERT MtiLLER, a subject of the German Emperor, andresiding at Essen-on-the-Ruhr, Germany, have invented certain new anduseful Improvements in Gas-Burners for Coke-Ovens, of which thefollowing is a specification.

My invention relates to coke-oven twyers, and a primary object is toprovide an improved burner-head for the same.

In horizontal coke-ovens gas for producing a high temperature issupplied to the combustion chamber through twyers constructed on theBunsen principle. The defeet is met with, however, that the gas and airare not mixed well but both flow from the twyers in separate jets.

According to my invention I bring about an intimate mixture of gas andair and a good distribution of the combustible mixture by means of aspecial burner-head. To this end I provide the burner-head with a numberof long ducts which are open laterally at their upper ends for a certainlength, so that the gases first mix and the mixture then emits infan-like jets.

One illustrative embodiment of my invention is represented by way ofexample in the accompanying drawing, wherein:

Figure l is a vertical longitudinal section through my improvedburner-head, and Figs. 2 and 3 are cross-sections in the planes AB andCD, respectively.

Referring to the drawing, a designates the burner-head which can beconnected in optional manner with the mixing tube and is closed at itstop end by solid material 6. This is traversed by ducts 0 of optionalcross-section, the top portions of which communicate laterally for acertain length through openings cl in the burner-head with the chambercontaining the same.

The number, shape, size and distribution Specification of LettersPatent.

of the ducts c depend on the conditions in each case, the kind of gasesto be burned and the size of the burner-head. Also the material of whichthe burner-head is made may be correspondingly optional if it befireproof, as c. g. clay, or non-combustible as c. 9. metal is, and soon. This burner is at the bottom of the coke-oven and gas is passed upthrough the mixing tube in which it receives a quantity of air accordingto the Bunsen principle, after which the mixture passes up through theducts 0 and out at the openings d.

I claim 1. A burner head for coke-ovens comprising a tubular portion,and a solid portion closing the end of the tubular portion, said solidportion being provided with longitudinal ducts having longitudinallateral openings therein, said solid portion entirely closing the end ofsaid tubular portion, except for said ducts having the lateral openings.

2. A burner head for coke-ovens comprising an upwardly projectingvertical tubular portion, and a solid portion in the upper end of thetubular portion and provided with a series of vertical ducts extendingparallel to and near the inner face of said tubular portion, each ductbeing provided With an elongated vertically disposed opening extendingoutwardly through said portions and establishing communication betweenthe ducts and the space around the head, and opening freely and directlyinto said space, said tubular portion being entirely closed except forsaid ducts having the openings.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
